Subject: Android: correctly report QMediaRecorder status.
X-Git-Tag: upstream/5.2.95+rc1~3^2~31
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=29ba8cf4c417d7c2ff9f2815bdc49c97215283a3;p=platform%2Fupstream%2Fqtmultimedia.git

Android: correctly report QMediaRecorder status.

QMediaRecorder should have the LoadedStatus before starting recording.
When recording the camera, the recorder should be considered loaded
when all prerequisites are met (viewfinder started, recording mode set
to video and capture ready).

Task-number: QTBUG-36828
